LUBRICATO R.

SPECIFICATION forming part of Letters Patent No. 330,192, dated November 10, v1885.

Application filed July 2, 1885.

To @ZZ whom it may concern.-

Beit known that I, HARRISON A. ANDREWs, a citizen of the United States, residing at Oonneaut, in the county of Ashtabula and State of Ohio, have invented certain new and useful Improvements in Lubricators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to theA letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to that class of lubricators used for lubricating line-shafts and other machinery so located that it cannot be easily reached.

It consists in the combination and arrangement of parts, as hereinafter described, and pointed out in the claims.

In the drawings, Figure 1 is a side elevation of a lubricator made according to my invention. Fig. 2 is a vertical section of the same.

a is a reservoir, of any desired form, and of suitable size to be easily handled, and is provided with a nipple, a', having an inlet-port, within which is located a stop-cock, a2. To the nipple a I attach an air-pump, Z), by which air is forced into the reservoir. The reservoir is provided with an outlet-pipe, c, arranged preferably near its upper end, and provided with a stop-cock, c', and adapted to support a pipe, d, of sufficient length to reach the shafts or gearing to be oiled. A discharge pipe or nozzle, d, is attached to the outlet-pipe, and is bent downward over each shaft, so as to discharge the oil into the cups, holes, or gearing. I have shown a metallic pipe, d, which is best adapted for oiling shafts arranged below ceilings, and of about uniform height from the floor.

Air is forced into the reservoir until the Serial No. 170,521. (No model.)

pressure is sufficient to force the oil through the pipe to the shaft. The flow is regulated by the stop-cock c.

By means of my peculiar construction and arrangement of parts a lubricating device is provided which is free from the complication of parts which is found in ordinary lubricators.

A stop-cock is placed between the air-pump and the reservoir, which may be closed and the pump removed entirely during usage, the pressure of the air remaining nearly the same.

The reservoir a is made of one piece of metal, and has a dome shaped top, which terminates in the nipple a', which performs the double office of a valve-seat for the stopcock or plug-valve a and a means of attachment for the pump-barrel. The lateral outletpipe c is also integrally formed with the body of the reservoir, and serves as a means of attachment for the discharge-pipe d.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

A lubricating device consisting of the following elements, in combination: a reservoir having a dome-shaped top terminating in a nipple, a plug-valve located in said nipple, a pump-valve registering with and secured directly to the mouth of the nipple, an outletpipe projecting laterally from and forming an integral part of the reservoir, a dischargepipe connected with said outlet-pipe, and a stop cock located in the base of the dischargepipe, the parts being arranged and operating substantially as shown and described.

In testimony whereof I affix my signature in presence of witnesses.

HARRISON A. ANDRFVS.
